Method and system for maintaining privacy in scoring of consumer spending behavior

ABSTRACT

A method for maintaining consumer privacy in behavioral scoring includes a first computing system and a second computing system. The first computing system disguises consumer characteristics and maps disguised consumer characteristics to unencrypted account identifiers, and then transmits the data to the second computing system. The second computing system encrypts the account identifiers upon receipt, and maps the encrypted account identifiers to anonymous transaction data. The second computing system uses the transaction data to calculate consumer behavioral scores, and then generates a scoring algorithm that uses disguised consumer characteristics to calculate consumer behavior scores based on the calculated consumer behavioral scores and corresponding disguised consumer characteristics. The generated algorithm is then returned to the first computing system, with the second computing system not receiving any unencrypted account identifiers, any undisguised consumer characteristics, or any personally identifiable information.

FIELD

The present disclosure relates to the maintaining of consumer privacy inbehavioral scoring, specifically the generating and use of scoringalgorithms that can maintain privacy via the use of disguised consumercharacteristics.

BACKGROUND

Many entities, such as merchants, advertisers, content providers,manufacturers, and more, are often greatly interested in finding out asmuch as they can about consumers. By learning more about consumers,these entities can often better target advertisements, offers, or othercontent to consumers, or better select consumers for receipt of specificcontent. As a result, these entities may try to obtain information onconsumers as often as possible, and with as much detail included aspossible. One such piece of information is transaction data associatedwith payment transactions involving a consumer. Such information may beuseful for identifying a consumer's purchasing behavior and shoppingtrends.

However, consumers may be worried about the amount of information thatadvertisers and other such entities may possess about themselves,particularly when it comes to their shopping behavior. As a result, manyregulations have been passed and/or adopted that may limit an entity'sability to gather and/or possess personally identifiable informationassociated with a particular consumer. Therefore, entities are now oftenin need for information about consumers that can provide valuabledetail, while still maintaining a consumer's privacy as per regulationsand requirements.

Thus, there is a need for a technical solution to provide behavioralscores for consumers based on transaction data while maintainingconsumer privacy.

DETAILED DESCRIPTION Glossary of Terms

Payment Network—A system or network used for the transfer of money viathe use of cash-substitutes. Payment networks may use a variety ofdifferent protocols and procedures in order to process the transfer ofmoney for various types of transactions. Transactions that may beperformed via a payment network may include product or servicepurchases, credit purchases, debit transactions, fund transfers, accountwithdrawals, etc. Payment networks may be configured to performtransactions via cash-substitutes, which may include payment cards,letters of credit, checks, financial accounts, etc. Examples of networksor systems configured to perform as payment networks include thoseoperated by MasterCard®, VISA®, Discover®, American Express®, PayPal®,etc. Use of the term “payment network” herein may refer to both thepayment network as an entity, and the physical payment network, such asthe equipment, hardware, and software comprising the payment network.

Personally identifiable information (PII)—PII may include informationthat may be used, alone or in conjunction with other sources, touniquely identify a single individual. Information that may beconsidered personally identifiable may be defined by a third party, suchas a governmental agency (e.g., the U.S. Federal Trade Commission, theEuropean Commission, etc.), a non-governmental organization (e.g., theElectronic Frontier Foundation), industry custom, consumers (e.g.,through consumer surveys, contracts, etc.), codified laws, regulations,or statutes, etc. The present disclosure provides for methods andsystems where the processing system 102 does not possess any personallyidentifiable information. Systems and methods apparent to persons havingskill in the art for rendering potentially personally identifiableinformation anonymous may be used, such as bucketing. Bucketing mayinclude aggregating information that may otherwise be personallyidentifiable (e.g., age, income, etc.) into a bucket (e.g., grouping) inorder to render the information not personally identifiable. Forexample, a consumer of age 26 with an income of $65,000, which mayotherwise be unique in a particular circumstance to that consumer, maybe represented by an age bucket for ages 21-30 and an income bucket forincomes $50,000 to $74,999, which may represent a large portion ofadditional consumers and thus no longer be personally identifiable tothat consumer. In other embodiments, encryption may be used. Forexample, personally identifiable information (e.g., an account number)may be encrypted (e.g., using a one-way encryption) such that theprocessing system 102 may not possess the PII or be able to decrypt theencrypted PII.

System for Maintaining Privacy in Behavioral Scoring

FIG. 1 illustrates a system 100 for the maintaining of privacy ingenerating behavioral scoring algorithms and application thereof toconsumer characteristic data.

The system 100 may include a processing system 102. The processingsystem 102 may be configured to generate scoring algorithms configuredto generate behavioral scores based on consumer characteristics usingthe methods and systems discussed herein. The consumer characteristicsmay be demographics, such as age, gender, income, residential status,marital status, familial status, zip code, postal code, occupation,education, etc. or other suitable types of characteristics that may beassociated with one or more consumers. The generated behavioral scoresmay be based on the consumer characteristics and may be indicative ofthe associated consumer or consumers' propensity for a certain type ofpurchase behavior.

For example, the processing system 102 may generate a scoring algorithmconfigured to score a consumer for their propensity to purchaseelectronic goods in the next thirty days, based on their consumercharacteristics. The types of purchase behavior that may be indicated bya score calculated using a scoring algorithm generated using the methodsand systems discussed herein may include propensities to spend at aspecific merchant or merchants, in a specific industry or industries, ata specific geographic location, during a specified period of time,within a specified range of transaction amounts, any combinationthereof, and any other behaviors that will be apparent to persons havingskill in the relevant art.

In exemplary embodiments, the processing system 102 may include two ormore computing systems and may be configured such that no individualcomputing system included in the processing system 102 may possessunencrypted transaction data and personally identifiable information atthe same time. In a first embodiment, discussed in more detail below,the processing system 102 may include a first computing system 106 and asecond computing system 108. In another embodiment, also discussed inmore detail below, the processing system 102 may include a firstcomputing system 106, a second computing system 108, and a thirdcomputing system 110. The computing systems 106, 108, and 110 discussedin more detail below, may be configured to perform the steps disclosedherein for the generation of scoring algorithms and the calculation ofbehavioral scores.

The system 100 may further include a requesting entity 104. Therequesting entity 104 may be an entity that is requesting a scoringalgorithm for calculating behavioral scores, or the behavioral scoresthemselves, for a plurality of consumers. The requesting entity 104 maytransmit data to the processing system 102 (e.g., to be received by thefirst computing system 106, which may not possess any personallyidentifiable information), which may include consumer characteristicsfor each of a plurality of consumers, and encrypted account identifiersfor each of the plurality of consumers.

In some embodiments, the processing system 102 may be configured todisguise the consumer characteristics to anonymize the data such that itmay not be personally identifiable. In one such embodiment, the firstcomputing system 106 may disguise the variables and/or values for eachof the consumer characteristics. For example, the consumercharacteristics may include demographics, including a gender variablethat has a value of male or female for each consumer. The firstcomputing system 106 may, after the data has been received from therequesting entity 104, disguise both the variable, gender, and thevalues, male or female, such that the information may not be used topersonally identify the related consumer, such as replacing the gendervariable with “X1” and replacing the male and female values with “A” and“B,” respectively.

The disguised values may then be used by the second computing system 108and/or third computing system 110 to generate a scoring algorithm basedon transaction data. Transaction data may be received from a paymentnetwork 112. The payment network 112 may receive and store transactiondata as part of the processing of payment transactions using methods andsystems that will be apparent to persons having skill in the relevantart. The payment network 112 may provide the transaction data to theprocessing system 102, which may be received by one of the includedcomputing systems. In an exemplary embodiment, the transaction data maybe received by the second computing system 108 and/or third computingsystem 110, but not the first computing system 106, such that nocomputing system in the processing system 102 possess both transactiondata and personally identifiable information. In such embodiments, thetransaction data may include only encrypted account identifiers and maynot include any unencrypted account information.

As discussed in more detail below, scoring algorithms may be generatedfor a specified type of consumer purchase behavior by the secondcomputing system 108 and/or third computing system 110 using thereceived transaction data, and may use disguised consumer characteristicvariables and values as part of the algorithm. For example, thealgorithm may use disguised variable X1 as an input for part of thescore calculation, and may expect a value of A or B for the variable.The scoring algorithm using the disguised characteristics as inputs maybe generated using transaction data for accounts and disguisedcharacteristics associated with each respective account. As discussed inmore detail below, the transaction data and disguised characteristicsmay be matched in the second computing system 108 and/or third computingsystem 110 using encrypted account identifiers such that no computingsystem in the processing system 102 possess both undisguisedcharacteristic data and transaction data.

The processing system 102 may be further configured to transmit agenerated scoring algorithm back to the requesting entity 104 inresponse to an earlier request. In instances where the requesting entity104 is requesting behavioral scores, the processing system 102 may firstscore each of the accounts for which characteristic data was receivedusing the generated scoring algorithm, and may return the scores to therequesting entity 104. In some embodiments, the first computing system106 may undisguise the characteristics included in the generatedalgorithm prior to transmission to the requesting entity 104.

Methods and systems discussed herein may thereby be enable to generatescoring algorithms using for identifying behavioral scores for consumersbased on consumer characteristics, while maintaining a high level ofconsumer privacy via the use of multiple computing systems. Bypartitioning the processing system 102 into multiple computing systems,none of which possess both transaction data and any personallyidentifiable information, the processing system 102 may be able toaccurately generate scoring algorithms without compromising consumerprivacy.

Computing Systems

FIG. 2 illustrates an embodiment of a computing system 200 of the system100. It will be apparent to persons having skill in the relevant artthat the embodiment of the computing system 200 illustrated in FIG. 2 isprovided as illustration only and may not be exhaustive to all possibleconfigurations of computing system 200 suitable for performing thefunctions as discussed herein. For example, the computer system 700illustrated in FIG. 7 and discussed in more detail below may be asuitable configuration of the computing system 200.

The computing system 200 illustrated in FIG. 2 and discussed herein maybe representative of each of the computing systems 106, 108, and 110included in the processing system 102. While it is discussed herein thateach of the computing systems 106, 108, and 110 may each include thesame components of the computing system 200 illustrated in FIG. 2, itwill be apparent to persons having skill in the relevant art that thecomputing systems 106, 108, and 110 may each include different and/oradditional components than those illustrated in the computing system200, and that each of the computing systems 106, 108, and 110 mayinclude configurations different from the computing system 200illustrated in FIG. 2.

The computing system 200 may include a receiving unit 202. The receivingunit 202 may be configured to receive data over one or more networks viaone or more network protocols. The receiving unit 202 may therebyreceive data from the requesting entity 104, which may include one ormore data files including encrypted account identifiers and consumercharacteristic data. Received data may also include behavior predictioncriteria and/or scoring requests. The receiving unit 202 in somecomputing systems 200 may also be configured to receive transaction datafrom the payment network 112. In some instances, received transactiondata may be associated with encrypted account identifiers and may notinclude any personally identifiable information.

In some computing systems 200, the receiving unit 202 may be configuredto encrypt data upon receipt. For instance, the receiving unit 202 ofthe second computing system 108 may be configured to encrypt accountidentifiers upon receipt such that the second computing system 108 doesnot possess any unencrypted account identifiers. In such an instance,the encryption may be performed by the receiving unit 202, or may beperformed by another component of the computing system 200 before thedata is made available to the rest of the system, such as an encryptingunit.

Encryption performed by the receiving unit 202 or other unit may be aone-way encryption, such that the encrypted data may not be unencrypted.Suitable encryption algorithms and methods of encryption that may beused will be apparent to persons having skill in the relevant art, suchas cryptographic hash functions (e.g., one or more of the SHA-2 set ofcryptographic hash functions). In some instances, a salt may also beused as part of the encryption.

The computing system 200 may also include a processing unit 204. Theprocessing unit 204 may be configured to perform the functions of eachcomputing system as discussed herein. In some instances, encryption maybe performed by the processing unit 204 in each respective computingsystem 200. The processing unit 204 may also be configured to identifyassociations in data received by the receiving unit 202 of therespective system. For instance, the processing unit 204 of the secondcomputing system 108 may, as discussed below, be configured to matchreceived transaction data with disguised consumer characteristics basedon associated encrypted account identifiers.

The processing unit 204 may also be configured to generate scoringalgorithms in some computing systems 200. Scoring algorithms may begenerated based on transaction data and associated disguised consumercharacteristics. In some embodiments, a scoring algorithm may begenerated to provide a score representing a specific consumer behavior,which may be a consumer behavior indicated in a request received by thereceiving unit 202 of a computing system 200 in the processing system102. The processing unit 204 may also be configured to calculatebehavior scores based on application of a generated scoring algorithm toa set of disguised or undisguised consumer characteristics.

In some computing systems 200, the processing unit 204 may also beconfigured to disguise consumer characteristics. Disguising consumercharacteristics may include disguising variables and/or their valuessuch that the corresponding undisguised variables and/or values may beunidentifiable to a computing system 200 that receives the correspondingdisguised characteristics. For example, if a consumer characteristic isa demographic indicating a consumer's income, where their income is oneof five predetermined ranges (e.g., less than $30,000, $30,001 to$50,000, $50,001 to $75,000, $75,001 to $100,000, and over $100,000),the processing unit 204 may disguise the values such that thecharacteristic of income may have a value of A, B, C, D, or E for aspecific encrypted account identifier. In some instances, the variableitself may also be disguised, such that a computing system 200 mayreceive the characteristic as characteristic X3 has a value of A, B, C,D, or E for each encrypted account identifier.

In some instances, processing units 204 that are configured to disguisedconsumer characteristics may also be configured to undisguise consumercharacteristics, such as in a received scoring algorithm. For example,the first computing system 106 may receive a scoring algorithm from thesecond computing system 108 that uses disguised variables and values,and the processing unit 204 of the first computing system 106 mayundisguise the variables and values prior to providing the generatedscoring algorithm to the requesting entity 104 in response to aninitially received request.

Computing systems 200 may also include a transmitting unit 206. Thetransmitting unit 206 may be configured to transmit data over one ormore networks via one or more network protocols. The transmitting unit206 may be configured to transmit data from one computing system 200 inthe processing system 102 to another computing system 200 in theprocessing system 102, such as the transmitting of disguised consumercharacteristics from the first computing system 106 to the secondcomputing system 108. The transmitting unit 206 may also be configuredto transmit data from a computing system 200 included in the processingsystem 102 to a system outside of the processing system 102, such as therequesting entity 104 and/or the payment network 112. For example, thetransmitting unit 206 of the first computing system 106 may beconfigured to transmit a generated scoring algorithm to the requestingentity 104.

Computing systems 200 may also include a memory 208. The memory 208 maybe configured to store data suitable for performing the functionsdisclosed herein. For example, the second computing system 108 may beconfigured to store received transaction data in the memory 208 prior tomapping the received transaction data to disguised consumercharacteristics. Data that may be stored in the memory 208 of variouscomputing systems 200 in the processing system 102 will be apparent topersons having skill in the relevant art.

Two System Process for Maintaining Consumer Privacy in BehavioralScoring

FIGS. 3A and 3B illustrate a process for maintaining consumer privacy inbehavioral scoring using the first computing system 106 and secondcomputing system 108 of the processing system 102.

In step 302, the first computing system 106 may identify (e.g., via theprocessing unit 204) account identifiers, wherein each accountidentifier is associated with a payment account corresponding to aconsumer. In some instances, the account identifiers may be stored inthe memory 208 of the first computing system 106. In step 304, therequesting entity 104 may identify consumer data for which behavioralscores are requested. The consumer data may include a plurality ofconsumer characteristics associated with each of a plurality ofconsumers, and an account identifier associated with each of theplurality of consumers.

In step 306, the requesting entity 104 may encrypt the accountidentifiers using a first one-way encryption and may transmit theencrypted account identifiers and corresponding consumer characteristicdata to the first computing system 108. The transmitted data may alsoinclude a scoring request, which may include a behavior predictionrequest corresponding to a purchase behavior for which the requestingentity 104 wants consumers to be scored. In step 308, the receiving unit202 of the first computing system 106 may receive the transmitted data.

In step 310, the processing unit 204 of the first computing system 106may disguise the received consumer characteristics. In some embodiments,the variables or values of the consumer characteristics may bedisguised. In other embodiments, both the variables and the values ofeach consumer characteristic may be disguised. In step 312, theprocessing unit 204 of the first computing system 106 may map theencrypted account identifiers received from the requesting entity withthe account identifiers stored in the memory 208 and identified in step302.

In step 314, the transmitting unit 206 of the first computing system 106may transmit the unencrypted account identifiers and their mappedconsumer characteristics to the second computing system 108. In step316, the receiving unit 202 of the second computing system 108 mayreceive the identifiers and mapped consumer characteristics and mayencrypt the account identifiers upon receipt using a second one-wayencryption. In some embodiments, the second one-way encryption may bedifferent than the first one-way encryption such that the encryptedaccount identifiers obtained by the second computing system 108 may bedifferent than the encrypted account identifiers transmitted to thefirst computing system 106 by the requesting entity 104.

In step 318, the receiving unit 202 of the second computing system 108may receive anonymous transaction data from the payment network 112. Theanonymous transaction data may include transaction data for a pluralityof payment transactions, wherein the transaction data for each paymenttransaction is associated with an encrypted account identifiercorresponding to a payment account involved in the respectivetransaction, where the encrypted account identifier is encrypted usingthe second one-way encryption. In step 320, the processing unit 204 ofthe second computing system 108 may match the anonymous transaction datato disguised consumer characteristics based on the respectivecorresponding encrypted account identifiers, and may score each of thematched sets of data. The scoring may be a behavioral scorecorresponding to the requested purchase behavior, and may be based onthe transaction data associated with each respective encrypted accountidentifier.

Once scores have been obtained that correspond to each encrypted accountidentifier, then, in step 322, the processing unit 204 of the secondcomputing system 108 may generate a scoring algorithm for the requestedpurchase behavior. The generated scoring algorithm may be configured tocalculate a behavioral score for a consumer based on disguised consumercharacteristics associated with that consumer. Accordingly, the scoringalgorithm may be generated based on the behavioral score for eachencrypted account identifier and the corresponding disguised consumercharacteristics.

In step 324, the processing unit 204 of the second computing system 108may be configured to calculate a behavioral score for each of therequested consumers using the generated scoring algorithm. In someinstances, the calculated score may be the same score identified foreach consumer in step 320. The transmitting unit 206 of the secondcomputing system 108 may transmit the consumer behavior scores to thefirst computing system 106.

In step 326, the receiving unit 202 of the first computing system 106may receive the consumer behavior scores. In step 328, the processingunit 204 of the first computing system 106 may generate a report of thecalculated consumer behavior scores. In some instances, the generatedreport may include the generated scoring algorithm or other informationthat may include disguised consumer characteristics. In such aninstance, step 328 may further include undisguising the disguisedconsumer characteristics. In step 330, the transmitting unit 206 of thefirst computing system 106 may transmit the generated report to therequesting entity 104 in response to the originally received scoringrequest. In step 332, the requesting entity 104 may receive thegenerated report.

In some embodiments, the requesting entity 104 may request the generatedscoring algorithm and not behavioral scores calculated using thealgorithm. In such an embodiment, steps 324 and 326 may not beperformed, and the report generated in step 328 may include thegenerated scoring algorithm transmitted from the second computing system108 to the first computing system 106, without any calculated behavioralscores included.

Three System Process for Maintaining Consumer Privacy in BehavioralScoring

FIGS. 4A-4C illustrate a process for maintaining consumer privacy inbehavioral scoring using the first computing system 106, secondcomputing system 108, and third computing system 110 of the processingsystem 102.

In step 402, the first computing system 106 may identify (e.g., via theprocessing unit 204) account identifiers, wherein each accountidentifier is associated with a payment account corresponding to aconsumer. In some instances, the account identifiers may be stored inthe memory 208 of the first computing system 106. In step 404, therequesting entity 104 may identify consumer data for which behavioralscores are requested. The consumer data may include a plurality ofconsumer characteristics associated with each of a plurality ofconsumers, and an account identifier associated with each of theplurality of consumers.

In step 406, the requesting entity 104 may encrypt the accountidentifiers using a first one-way encryption and may transmit theencrypted account identifiers and corresponding consumer characteristicdata to the first computing system 106. The transmitted data may alsoinclude a scoring request, which may include a behavior predictionrequest corresponding to a purchase behavior for which the requestingentity 104 wants consumers to be scored. In step 408, the receiving unit202 of the first computing system 106 may receive the transmitted data.

In step 410, the processing unit 204 of the first computing system 106may disguise the received consumer characteristics. In some embodiments,the variables or values of the consumer characteristics may bedisguised. In other embodiments, both the variables and the values ofeach consumer characteristic may be disguised. In step 412, theprocessing unit 204 of the first computing system 106 may map theencrypted account identifiers received from the requesting entity withthe account identifiers stored in the memory 208 and identified in step402.

In step 414, the transmitting unit 206 of the first computing system 106may transmit the unencrypted account identifiers and their mappedconsumer characteristics to the second computing system 108. In step416, the receiving unit 202 of the second computing system 108 mayreceive the unencrypted account identifiers and mapped consumercharacteristics and may encrypt the account identifiers upon receiptusing a second one-way encryption.

In step 432 the processing unit 204 of the third computing system 110may be configured to calculate a behavioral score for each of therequested consumers using the generated scoring algorithm. In someinstances, the calculated score may be the same score previouslyidentified for each consumer and received by the third computing system110 in step 428. In step 434, the transmitting unit 206 of the thirdcomputing system 110 may transmit the consumer behavior scores to thefirst computing system 106.

In step 438, the processingunit 204 of the first computing system 106 may generate an undisguisedreport of the calculated consumer behavior scores. In some instances,the generated report may include the generated scoring algorithm orother information that may include disguised consumer characteristics.In such an instance, step 438 may further include undisguising thedisguised consumer characteristics. In step 440, the transmitting unit206 of the first computing system 106 may transmit the generated reportto the requesting entity 104 in response to the originally receivedscoring request.

In such an embodiment, steps 432-436 may not be performed,and the report generated in step 438 may include the generated scoringalgorithm transmitted from the third computing system 110 to the firstcomputing system 106, without any calculated behavioral scores included.
